Grind Stormer, called V-Five or V-V (ヴイ・ファイヴ) in Japan, is a 1992 arcade shoot-'em-up developed by Toaplan. It was ported to the Sega Mega Drive in 1994 and released by Tengen exclusively in the US and Japan.

Gameplay

Grind Stormer: more conventional weapon upgrades, with / shooting and dropping a bomb

You can select which mode to play in the Options Menu by pressing at the title screen. Also during gameplay, you always have two auxiliary guns at your sides — and move them toward your front/rear. When at the front, the shots combine with yours to form a more powerful shot; when at the rear, you have a spread shot. Regardless of configuration, you can hold / to rapidfire.

Some (many?) American copies of the game are plagued with a manufacturing defect (supposedly poor quality PCBs?) that reduce the cartridge's lifespan.
